Determination of cyclosulfamuron in agricultural products by HPLC

Simplified determination of cyclosurfamuron in agricultural products by HPL C with a UV detector was investigated. The homogenate of agricultural products was extracted with acetone. The cru de extract was partitioned between 10% sodium chloride solution and ethyl a cetate-n-hexane(1 : 1)solution, and the ethyl acetate-n-hexane layer was ev aporated to dryness. The residue was dissolved in n-hexane, and after the s olution had been refined with ACCUCAT(TM), the methanol solution was analyz ed by liquid chromatography. Cyclosulfamuron was detected in terms of the a bsorbance of 260 nm. Recoveries at the 0.1 ppm level were more than 73% from agricultural produc ts. Detection limits were 0.01 ppm in samples.
